EXHAUSTOProductsModular unitsVEX4000, modular air handling unitsCrossflow heat exchanger (EX) Crossflow heat exchanger (EX) The classic crossflow heat exchanger can be a good choice, especially as the two air streams are completely separate, avoiding passage of contaminated or moist air from the extract air to the supply air. Merge to pdf Function and application VEX4000 crossflow heat exchanger Description The classic crossflow heat exchanger secures stable, economic operation and meets the requirement for separated air streams, so that neither contaminated air nor humidity are transferred from extract air to supply air. A crossflow heat exchanger can achieve a temperature efficiency of up to 73 %, which can be an advantage in buildings with too high a heating surplus. At low outdoor temperatures, condensate is separated from the warm air stream, thus allowing part of the latent heat to be recovered. VEX4000 EX By-pass For regulating the heat exchanger's performance, there are integral by-pass ducts which allow the outdoor air to be wholly or partly diverted round the heat exchanger. This can be utilised in the shoulder seasons, where there is no need for full heat recovery. Condensation outlet The crossflow heat exchanger section is fitted with corrosion resistant base trays, with a fall to the drain, allowing cleaning of the heat exchanger while mounted in the unit. The condensation drains have smooth piping and exit the panel on the operating side, where a water trap should be fitted. Design options Options: standard crossflow heat exchanger in aluminium -for extraction and other purposes with no special requirement for high efficiency high-performance crossflow heat exchanger in aluminium - for higher efficiency ratings high-performance crossflow heat exchanger in aluminium ERP 18 - for extra high efficiency epoxy-coated crossflow heat exchanger for particularly corrosive environments Merge to pdf Dimensions, dimensions table for EX module EX, heat exchanger section with crossflow heat exchanger Dimensions table VEX4000 model Height Length Depth VEX4010 [mm] 1309 1038 1055 VEX4020 [mm] 1309 1038 1275 VEX4030 [mm] 1499 1180 1549 VEX4040 [mm] 1599 1320 1630 VEX4050 [mm] 1744 1320 1755 VEX4060 [mm] 2069 1468 1930 VEX4070 [mm] 2069 1468 2115 VEX4080 [mm] 2494 1610 2325 VEX4090 [mm] 2744 1893 2625 VEX4100 [mm] 3024 1893 2895 The indicated dimensions are the dimensions for the section - EXselectPRO gives the correct dimensions for the whole air handling unit, including assembly fittings and seals.
